Monthly atmosphere support data (Aqua AIRS, 1 deg)
What it measures. Monthly, gridded atmospheric 'support' data such as inputs and intermediate values behind the main AIRS atmosphere products. These are extra fields, some not fully checked for quality.
How it's made. Produced from the AIRS infrared sounder on the Aqua satellite, averaged into monthly 1-degree grid boxes where each box is the average of the measurements falling inside it.
How & where you'd use it. A behind-the-scenes input mostly for specialists; because some values come from failed retrievals and lack quality flags, it is used with care rather than as a finished product.

Official description
The Atmospheric Infrared Sounder (AIRS) is a grating spectrometer (R = 1200) aboard the second Earth Observing System (EOS) polar-orbiting platform, EOS Aqua. In combination with the Advanced Microwave Sounding Unit (AMSU) and the Humidity Sounder for Brazil (HSB), AIRS constitutes an innovative atmospheric sounding group of visible, infrared, and microwave sensors. The L3 support products are similar to the L3 standard products but contain fields which are not fully validated, or are inputs or intermediary values. Because no quality control information is available for some of these fields, values from failed retrievals may be included. The value for each grid box is the sum of the values that fall within the 1x1 area divided by the number of points in the box.
